WebThe Hilber–Hughes–Taylor time-integration scheme is used to calculate the dynamic response parameters of the double-channel rectangular cross section tunnels. Considering fixed excavation steps in the process of shield crossing, acceleration and deformation of the existing tunnels were analyzed under the moving-axle loads of trains at ... WebApr 10, 2024 · The Abaqus user subroutine options are used to solve the displacement field and phase field iteratively. For dynamic cases, Abaqus adopts the Hilber-Hughes-Taylor (HHT) method, a more common case of the New-mark method, to acquire the equilibrium. HHT is a built-in solver and solves the linearised equilibrium by Newton-Raphson iteration.
WebHilber, Hughes, and Taylor (1978)present cogent arguments for the use of Equation 2.4.1–2–Equation 2.4.1–4for integrating structural dynamics problems. The main appeal of the operator is its controllable numerical damping and the form this damping takes, slowly growing at low frequencies, with more rapid growth in damping at high frequencies.
